2. Differential Manometers

Try these first

1. 1.

   Define what a differential manometer does in fluid mechanics.

   Hint

   Look at the definition and think about its application.

2. 2.

   What is specific weight (γ)?

   Hint

   Consider why we need it in pressure calculations.

3. 3.

   What does a differential manometer measure?

   • Pressure of a single fluid
   • Pressure difference between two points
   • Fluid density

   Hint

   Think about what 'differential' means.

4. 4.

   True or False: The pressure increases with fluid height in a manometer.

   • True
   • False

   Hint

   Recall the hydrostatic pressure formula.

5. 5.

   Create a scenario where the pressure difference between two fluids in a manometer setup leads to a specific engineering application. Calculate that pressure difference given fluid heights and densities.

   Hint

   Set up a diagram to assist your calculations.

6. 6.

   Design a simple experiment to observe the principles behind differential manometers using accessible materials. Describe your findings.

   Hint

   Think about measuring fluid levels and compare pressures.
